Serial and Parallel
What voltages will be read at points R2 A, B, and C?

3.

Serial and Parallel
Find the total current and Voltage at R4.

4.

Voltage Dividers with Resistive Loads
A voltage divider consists of 56kOhm two resistors and a 15 V source. Calculate
the unloaded output voltage taken across one of the 56kOhm resistors. What will
the output voltage be if a load resistor of 1MOhm is connected across the
output?
